Geomagnetic field — magnetic field of the Earth — measured in any point of earth surface is the totality of several magnetic fields, generated by different sources. This fields superimpose and interact one with other. More than 90% of measured field is generated inside the planet and in the Earth crust.
- Geomagnetic data on the site of Russian WDC on Solar-Terrestrial Physics archive of magnetograms and digital data about magnetic field of the Earth.
- INTERMAGNET — global network of Earth magnetic field observation stations. Archive of magnetograms and digital data about magnetic field of the Earth.
- Data about quantity of geomagnetic pulse depending on their frequency on the results INTERMAGNET array processing.
